  • Patent number: 11911054
    Abstract: Described herein is a neuroaspiration catheter for removing a blood clot in a blood vessel. The neuroaspiration catheter includes a first tube, a second tube and a wire for guiding the navigation of the catheter. The wire can be navigated to the site of the blood clot, aid the navigation of the catheter, and left in the blood vessel during and after the aspiration. If the aspiration fails, the catheter can be quickly navigated back to the site of the blood clot using the wire as a guide. Also described herein is a method of removing a blood clot using the neuroaspiration catheter.

  • Patent number: 11911572
    Abstract: A balloon retention urinary catheter includes a porous and spongy distal tip. In one method, a polymer is mixed with sacrificial particles and the mixture is molded in the form of the tip, and then cured. The cured tip is then placed in a solvent in which the sacrificial particles elute from the tip but in which the polymer is insoluble. Once the particles elute out of the polymer in the tip, a softer porous polymeric structure results. The tip may be structured to be softer prior to use or for transformation to a softer state once in the bladder.

  • Patent number: 11904106
    Abstract: The invention provides an improved indwelling urinary catheter of the inflatable type having a unique, low profile device by which to retain the catheter within the bladder, so that urine can be removed therefrom while avoiding obstruction to the descending fetal vertex during the process of labor and delivery. Thus, making it better suited for obstetrical applications. The retaining device consumes less obstructing volume in the bladder than that which would ordinarily be consumed by a conventional Foley-style balloon, whereby both the frequency and severity of fetal vertex obstruction and its resulting increased time of labor, operative delivery and injury to maternal urologic tissue can be reduced. The obstetrical foley retains the tradition Foley-style balloon distal to the improved low-profile laboring balloon for insufflation in the event a surgical delivery by cesarean section is indicated.

  • Patent number: 11896755
    Abstract: A chest drainage system including a collection device configured to receive fluid from the pleural cavity of a patient. A sensor is included to detect a pressure differential in the fluid. A display is configured to display a trend in occurrences of changes in pressure of the fluid over time in predetermined time increments based on a number of detections of pressure differentials that exceed a predetermined pressure differential during each of the predetermined time increments. The trend is correlative to the percentage of time that the patient is deemed to have an air leak in the pleural cavity in the predetermined time increments. The trend is derived from a ratio of the quantity of respiratory cycles of the patient for which the predetermined pressure differential is detected (QRCleak) in the predetermined time increments to the total quantity of respiratory cycles of the patient in respective predetermined time increments (QRCtotal).

  • Patent number: 11872352
    Abstract: The presently described catheter is an improved multi-function hypospadias catheter adapted to be urethrally inserted and secured within a patient's bladder using an attached internal crescent shaped retention balloon. The inverted crescent configuration of the balloon reduces the contact surface area between the balloon and a patient's bladder wall to reduce bladder spasms. The catheter is removed from the patient (when needed) via deflation of the crescent shaped balloon, which deflates completely so as to not contact a patient's urethra during insertion and removal of the catheter. The catheter includes a double lumen with a one-way flow valve. One lumen provides a passageway to drain urine from a patient's bladder. The second lumen provides a passageway to inflate and deflate the crescent shaped retention balloon.
